A scuba diver films one of several large 3' - 5' long Potato Cod ( Epinephelus tukula) that frequent the famous 'Cod Hole' dive site on the Great Barrier Reef in North Queensland, Australia.
There are frequent feedings of the Potato Cod's at this site, though in general only one or two of the Cod participate. The rest can generally be found resting on a variety of coral reef heads being cleaned by the various species of cleaning fish found in the area.
These grouper can grow as large as 7' in length and are generally docile and curious, although the occasional aggressive incident towards scuba divers have occurred.
